[asterisk-users] NAT issue with Fortinet Firewall

I have a customer with a Fortinet Firewall that is having stability
issues with Asterisk and SIP endpoints (PAP2T) outside his network.  

	The first issue I see is that Asterisk sees all phones as the IP
address of the Fortinet.  Since the parameter "localnet" defines the
local network and that address falls in that range, how will Asterisk
treat the endpoints?  I have "nat=yes" for all phones and
"canreinvite=no" as well.  The "externip" parameter is set
to the
outside public IP address.  Still we have calls with one way audio.

	This is the first setup with a firewall that rewrites the IP address of
the endpoint so I do not know how that is affecting the packet flow.  On
my other servers I can always see the public IP of the endpoint.

[asterisk-users] NAT issue with Fortinet Firewall

Fortinets have a SIP session-helper. Sometime this causes issues,
try turning it off. To do this you need to enable telnet on the
forinet management interface. Telnet into the cli and type the following

config system session-helper
edit 12
set port 5066
end

Instead of turning this off or taking it out I am changing the port
so it will not affect 5060 anymore. This way you can put it back if
this doesn't work for you.

[asterisk-users] NAT issue with Fortinet Firewall

FYI, I have probably 10 Fortinet units with multiple SIP phones behind 
each and all of the phones work flawlessly.  As long as the Fortinet is 
ver 3.0 or newer, it does NAT so that you don't need to have nat=yes on 
*.  No pinholes or static nat or anything, it just works.

As a side note, I probably have 20+ Cisco PIX's with the same setup and 
they work flawlessly too.  I've seen a lot of people saying "fixup
sip"
breaks phones, but not that I have seen.  I just let the PIX do nat and 
it works fine.

[asterisk-users] cdr_custom outout to serial port

Hello,
I have a system in a motel that needs call billing data output through its
serial port so the existing motel management software can collect the call
billing info.
Is there any easy way to redirect the data that goes into the
cdr_custom/Master.csv file to go out the serial port ?

The system is Asterisk 1.4.18.1 on Centos 5.1

Thanks,
Col

[asterisk-users] cdr_custom outout to serial port

Hello again,
I can copy the file out the serial port by doing this:

rename Master.csv out1.csv
cat out1.csv > /dev/ttyS0

If I build a script to do this every 10 or 20 seconds via cron I think it
will work fine, unless someone has a better way.

Cheers,
Col

[asterisk-users] cdr_custom outout to serial port

Thanks for the idea Zoa.

I've got the cronjob working every minute now using

if [ -f /var/log/asterisk/cdr-custom/Master.csv ]
  then
    cd /var/log/asterisk/cdr-custom
    mv -f Master.csv out1.csv
    cat out1.csv > /dev/ttyS0
fi

Using tail -f would give me the realtime output, but a few questions as a
real linux novice;
What would be the best way to start this up ?
How would I monitor it to make sure it hasn't died, and how to restart ?

Cheers,
Col
